InitStateModelColumn
Specifies the name of the model attribute column in the InitStateProb table.
InitStateColumn
Specifies the name of the state attribute column in the InitStateProb table.
InitStateProbColumn
Specifies the name of the initial probability column in the InitStateProb table.
TransAttributeColumn
Specifies the name of the model attribute column in the TransProb table.
TransFromStateColumn
Specifies the name of the source of the state transition column in the TransProb table.
TransToStateColumn
Specifies the name of the target of the state transition column in the TransProb table.
TransProbColumn
Specifies the name of the state transition probability column in the TransProb table.
EmitModelColumn
Specifies the name of the model attribute column in the EmissionProb table.
EmitStateColumn
Specifies the name of the state attribute in the EmissionProb table.
EmitObsColumn
Specifies the name of the observation attribute column in the EmissionProb table.
EmitProbColumn
Specifies the name of the emission probability in the EmissionProb table.
ModelColumn
Specifies the name of the column that contains the model attribute. Then model_column must match a model_key in the PARTITION BY clause.
SeqColumn
Specifies the name of the column that contains the sequence attribute. The sequence_column must be a sequence attribute in the PARTITION BY clause.
ObsColumn
Specifies the name of the column that contains the observed symbols.
Observed symbols are case-sensitive.
Incremental
[Optional] Specifies whether to compute only new sequence probabilities. Default: 'true'.
If you omit the SeqProbColumn argument, the function cannot determine whether the observed sequence is new; therefore, it treats all model sequences in the input tables as new.
ShowChangeRate
[Optional] Specifies whether to show the percentage change that corresponds to the applied model with the difference from previous predicted probability. Default: 'true'.
SeqProbColumn
[Optional] Specifies the name of the column that contains the values for calculating the change rate.
SkipColumn
[Optional] Specifies the name of the input column whose Boolean values determine whether the function skips the row.
Accumulate
[Optional] Specifies the names of the input_table columns to copy to the output table.
